FABRIC FOR AIR GOODS.

Specification of Letters Patent.

Patented J an. 30, 1906.

Application filed June 12,1905. Serial No. 26 L950.

To all whom it may concern:

Be it known that I, HENRY FRANGIs KEIL, a citizen of the United Statesof America, and a resident of Bronxville, in the county of Wcstchesterand State of New York, have invented a certain new and useful Fabric forAir Goods, of which the following is a specification, the same being afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to inflatable and deflatable beds, cushions, andanalogous devices, and has especial relation to the construction of afabric for mattresses and the like, which mattresses ordinarily havetiepieces or stays extending from the upper and lower portions thereofdesigned to be used with a view of keeping the parts of the cushion,&c., in proper relative position and of strengthening the entire body ofthe same, the said beds, 620., being easily portable and when inflatedbeing comfortable, so as to readily conform to the different positionstaken by the user, which beds, &c., will retain the air under all normalconditions; and ithas for its object the provision of an article of theclass described which will be economical to manufacture and BII'IGIGDI]and durable in ractical use.

With this object in view the invention con sists in certain novelfeatures of construction and arrangement of parts, all of which will behereinafter described, and specifically pointed out in the drawingswhich accompany and form a part of this specification, and in whichFigures 1 and 4 represent plan views of fabrics for air goodsconstructed according to my invention. Figs. 3 and 6 are side elevationsof the fabric shown, respectively, in Figs. 1 and 4, havingoppositely-disposed stays attached together; and Figs. 2 and 5 areelevations looking sidewise at Figs. 1 and 4, respectively.

Like letters of reference indicate like parts in all the views.

Referring particularly to the drawings, A denotes a fabric suitable tobe used in the construction of inflatable beds, cushions, or likepneumatic devices made of suitable flexible sheet material. Heretoforestays or tiebands for holding the upper and lower fabrics of a cushion,bed, &c., together have been constructed. independently of the saidfabrics and separately applied to the fabric subsequent to thecompletion of the same, the said stays or tie-bands being ordinarilyattached or fastened to the fabric after the same has been treated witha coating of an air-proof and preferably elastic material, as rubber. Ina pneumatic mattress made according to my invention, however, the fabricand the ends of the stay are held together by means of flexible threadsor filaments, as by having the said stay-ends woven in and forming apart of the said fabric, as in Figs. 1 to 3, where the stay-ends a areformed of loops of thread which are dropped in the process of weavingthe fabric A, which fabric and stayends are thus held together by meansof flexible threads or filaments. Small rings a are passed through thesaid loops, which, together with suitable connecting means, as rings Aor hooks A, serve to hold the oppositely-disposed pairs of stay-endstogether.

In the fabric A (shown in Figs. 4 to 6) are woven flat cross loops orstays a for use in. cases where great streiiigth of material isrequired. Small rings or rivets of serve as a means for attachment ofthe cord a and snap hooks A to the oppositely disposed pairs ofstay-ends a My fabric may be treated with a coating of air-proofmaterial, as rubber, in any suitable or desired manner. The said fabricwill be found to be very economical in construction and also verydurable and serviceable in use and inexpensive to be made up intocushions, mattresses, and the like.

Having thus described and ascertained the nature of my said inventionand in what mannor the same is to be performed, it being kept in mindthat in law the substitution of equivalents works no variation in thesubstance of the same, I would have it understood that what I claim asmy invention is- 1. In air goods a series of loops of thread dropped atintervals to form a stay-end, said loops being held together betweentheir ends by flexible threads or filaments.

2. In a fabric for air goods a series of loops of thread dropped atintervals to form a stayend, said loops being held together between.

their ends by flexible threads or filaments, in combination with acoating of air-proof material applied to the said fabric.

3.
